THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED.

ANDERSON COOPER, CNN ANCHOR: Good evening, everyone.

There is a lot of news to tell you about tonight about the bombing suspect, his dead brother and what drove them to do what they allegedly did. We will touch on all of that tonight, including new details from the surviving suspect's hospital bedside, court proceeding and the one single word he uttered as well as a close-up look at the government's case against him, the information coming from an FBI affidavit.

Also tonight, an exclusive interview with the SWAT team members who helped to apprehend him or actually put the handcuffs on the suspect. The hour is about much more than that.

Earlier today, a local newspaper columnist said people here in Boston had many more important things to worry about than the guy who did this. Mourning their dead, healing their wounds and living their lives. Not making an alleged killer and would-be mass murderer the center of all the attention. And that's a good message we think tonight.

Late today, a week after two bombs went off there, the FBI handed control over that stretch of Boylston Street back to the city, beginning the process of turning a crime scene back into one of Boston's main arteries. As I said, there is a lot to tell you about.

With dignitaries gathered, a bagpipe playing, the flag which has been flying at half staff for the last week was lowered and folded. Earlier today, at ten to 3:00, that same stretch of Boylston, all corners of Boston, Watertown and beyond, fell silent. Silence fell over Washington as well, including the White House, where President Obama observed the moment, traders on Wall Street joined him as well. Silence for the three whose lives were taken in the bombing, Krystle Campbell, Martin Richard and Lingzi Lu as well as for fallen MIT police officer Sean Collier, gunned down Thursday night allegedly during the suspects' flight to Watertown. We honor them all tonight as we have this past week.

A short time ago, people gathered on the Boston University campus as well to Remember Lingzi Lu, who came here from China to pursue a graduate degree in applied math. Her family says that while she was here, she fell in love with this city. Tonight, this city returned that love.

We also honor the bravery of a young woman I spoke to, a dancer who lost a foot and part of her leg in the bombings but vows tonight she will dance again. You will hear from her when we visit her in her hospital room and her husband as well.

There's also late word on the terror plot that authorities in Canada say they have broken up. We begin, though, with a very full day here in Boston and our "360's" Randi Kaye.

(BEGIN VIDEOTAPE)

RANDI KAYE, CNN CORRESPONDENT (voice-over): Exactly one week after the bombs went off, there remain as many questions as answers. The man to answer most of them, suspect Dzhokhar Tsarnaev, remains in a hospital bed.

Sources tell CNN he is communicating with investigators, but would not elaborate. The sources say investigators want to know if the public is safe, if there are other bombs and who, if anyone, might have put the Tsarnaev brothers up to this.

Tsarnaev was formally charged today with using a weapon of mass destruction against persons and property. Then, late this afternoon, the "New York Times" published a transcript of the legal proceedings, during which the defendant could only nod in agreement when asked if he would answer some questions. A judge in his hospital room told him if I ask you any questions here in this hearing which you think might incriminate you, you have the right not to answer. Again, a nod he understood. He also asked if he could afford a lawyer. The defendant mumbled no.

According to the FBI affidavit, also released today, new details about the crime itself and the manhunt that followed. Turns out just 11 minutes before the bombs went off, the suspects were seen turning on to Boylston Street, and on Friday night, when police picked up the younger brother, they found in his pockets a university of Massachusetts I.D. card and other forms of identification. All of them identified him as Dzhokhar Tsarnaev.

The affidavit also says his dorm room was searched. There, investigators found quote "a large pyrotechnic, a black jacket and white hat that matched the same general appearance as those worn by bomber two." They also found bbs.

Until Dzhokhar Tsarnaev speaks, if he does, there are still so many unanswered questions. Were the suspects planning more attacks? The police commissioner wouldn't comment on a specific target, but says they were well stocked with ieds, pipe bombs and a whole lot of fire power.

EDWARD DAVIS, COMMISSIONER, BOSTON POLICE DEPARTMENT: I saw that with my own eyes. I believe that the only reason that someone would have those in their possession was to further attack people and cause more -- more death and destruction. KAYE: Another key question, why was this jihadist leader on the older brother's You Tube channel. Tamerlan Tsarnaev had apparently posted and removed this clip, found under the subheading terrorists, it shows the militant Abu Dujana (ph), he was killed in December. Tamerlan Tsarnaev had created this You Tube channel in August 2012, shortly after a visit to Russia. Did the suspect have any connections to the jihadist group? Could he have received orders from them? Still unknown.

What we do know, according to members of this Boston area mosque, is that he became increasingly radical in recent years. In January, he had an outburst during Friday prayers. A mosque leader had been praising Mohammed along with martin Luther King, Jr.

ANWAR KAZMI, BOARD MEMBER, ISLAMIC SOCIETY OF BOSTON: Some people said that he said something to the effect that you cannot, you know, compare or make a parallel between a prophet and a non-Muslim. Some people said that he referred to the person who was giving the sermon as a hypocrite. The word is monophyte (ph).

KAYE: As investigators wait for answers, loved ones say good-bye.

At a church in Medford, Massachusetts, hundreds of family and friends said good-bye to Krystle Campbell. She had gone to watch a friend in the race and died near the finish line. She was remembered as beautiful, fun and lovely.

(END VIDEOTAPE)

COOPER: Krystle Campbell was just 29-years-old. That was Randi Kaye reporting.

Here's another perspective on the capture of the suspect Friday. New infrared video of him inside that boat, the boat he was eventually captured in, he was eventually handcuffed by members of a SWAT team. We will hear from some of them later in the program tonight.

DREW GRIFFIN, CNN INVESTIGATIVE CORRESPONDENT: Well, I mean, they laid it out pretty well in the criminal complaint. The criminal complaint against this one surviving suspect. But overall, there is a national security investigation under way to answer that one question we all want to know. Is this it? Are these just the two guys involved or is there somebody else?

Right now, there is nothing to indicate that there was anybody else involved but you have to be 100 percent sure. So they are going to go through everything they purchased, everybody they contacted, every phone call they made, to make sure nobody was involved or even unwittingly involved in aiding these kids. COOPER: Jeff, in terms of the legal case, I want to read a portion from the transcript of the hearing in the hospital room today, the subject's hospital room. The judge said quote "at this time, the conclusion of the initial appearance, I find that the defendant is alert, mentally competent and lucid. He is aware of the nature of the proceedings."

What's your assessment, Jeff, of the initial hearing and the fact that the Obama administration decided to try him in civilian court rather than as an enemy combatant in a military tribunal?

JEFFREY TOOBIN, CNN LEGAL ANALYST: Well, I think the military tribunal was a complete nonstarter. There has never been an American history in an American citizen arrested on American soil charged in a military tribunal. It's just simply never going to happen. It certainly didn't happen in the Bush administration. It didn't happen in the Obama administration, so that was never -- that's just not -- it's irrelevant at this point.

Now, the case is under way. The fact that he was well enough to be arraigned on the complaint means now that the government will move to present this case in the grand jury, probably within a month there will be an indictment, and then the case will move to a federal district court.

At that point, I expect things will slow down quite a bit. I would be surprised, given the magnitude and complexity of this case, that there could be a trial inside of a year, but at least now the process is under way.

COOPER: Juliette, from a law enforcement standpoint, do you think it was the right decision to try him in civilian court?

JULIETTE KAYYEM, CNN NATIONAL SECURITY ANALYST: Absolutely. Like what Jeff said, there is just really no debate about this. It's more of a political debate. For one, the law doesn't even cover him because he's a U.S. citizen. But from a law enforcement national security perspective, what better way to minimize the impact of terrorists than to treat them like criminals. I mean, that's what they are. And if you make them into sort of a bigger deal than he is or anyone is, it sort of gives them a relevance we actually don't want to.

So, a lot of people in national security and counterterrorism love this idea. Not only because of the legal underpinnings behind it but also because it sort of says to anyone who would harm us, you are just a criminal.

COOPER: There has also been a lot of successful prosecutions of terrorist suspects in criminal court.

KAYYEM: And you can learn a lot of evidence from this. When I first got into this field it was right after the Africa bombings, African embassy bombings in '98, and some of the testimony that came out of that really taught us a lot about bin Laden, about his rise within Islamic jihadism and you can learn a lot out of it. What we don't know is whether he has anything to teach us. That's the one problem. How involved was he with others.

COOPER: Sanjay, we have heard little bits here and there from sources and also public sources about the medical condition of this suspect. What are you hearing that stands out to you?

DOCTOR SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT: You know, sort of looking at some of the pictures and looking at the timeline, you saw him standing, for example, the time that he was captured. That's very important in terms of trying to get an idea of the type of injuries that he had. I've heard that he had this injury to the neck. There's two questions that you are always going to ask. Was a major blood vessel injured because that can be a catastrophic life threatening injury.

COOPER: By the way, I talked to a member of the SWAT team, one of the men who apprehended him, actually it was in the final assault by the boat, and I asked him about that injury because there were reports some people said it was self-inflicted, some said it was a gunshot wound. He seemed to say, from his vantage point, he said it looked like more of a knife wound as opposed to a gunshot. But again, that's his vantage point.

GUPTA: That would sort of fit. It did not appear a major blood vessel was hit. That's one of the first questions. The other question people want to know, was the spinal cord injured. And there's two things that have sort of come up. One is he was just standing at the time you saw the pictures of him standing, he wouldn't be able to do that with a cervical -- with an injury in the neck to the spinal cord. And there's also this idea that he may have been writing as well which is important not only because you can hear, process and be able to communicate in this way, but also just the physical act of writing is so important.

COOPER: Right. A source saying he was actually writing in responses to some of the questions. There's also a report he was just sort of nodding the affirmative or negative.

I want to read some from what we learned happened in the hospital room. The judge said to him can you afford a lawyer. Then the defendant said no. The judge said let the record reflect I believe the defendant has said no. From that, clearly, I mean, his ability to communicate is limited. Does he have something in his throat?

GUPTA: Yes. My guess is, two things. First of all, just the communication, again, he understood the question, he was able to vocalize or at least make a response. Whether he mouthed the word or he actually made an audible sound, it wasn't clear. I read that very carefully as well.

But there probably likely is something in the throat because there almost always is when someone has a neck injury. It's one of the operations that surgeons are going to perform. You need to protect the airway. Even with that thing in the throat, sometimes you can make a sound or you can mouth the word no, for example. It would be clear enough that he's, in fact saying no.

COOPER: Right.

Juliette, in terms of the investigation, and Drew as well, I mean, it's not just the investigation here, obviously it's also overseas from the intelligence community, not only checking signals intelligence and the like, but also trying to find out information about what he was doing in Russia for that six-month period, his brother.

GRIFFIN: Yes. I think we've seen it in many other cases, what's the inspiration here, what's the motive. Was it a person, were there any e-mails. We have had, you know, Hassan had e-mails back and forth with a Muslim -- so they're going to want to know just for intelligence reasons to figure out where this inspiration came from, if from anywhere, just so they can learn more about these kinds of threats in the future.

KAYYEM: And this is, I mean, this is something, this is quite common that the investigation would engage allies or people we have not great relationships with right now such as Russia, to get them engaged with the investigation. I think the biggest question right now is really what was Russia doing with him? If they were so concerned about him, how much were they investigating him, how much were they following him when he was actually in Russia. And that is going to be a big question mark because if both intelligence agencies or investigative agencies thought that he was sort of fine, then that may make sense to us sort of in terms of our own investigation. But this is quite normal. We are seeing it in Canada today with the arrests, these kind of bilateral investigations.

COOPER: And Jeff, we know he spent time with relatives in Dagestan. He also is said to have visited Chechnya. But, there are gaps in our knowledge of exactly what he did and who he met with there. In terms of building the case, though, Jeff, what are the next -- the next steps? I mean, you are saying this could be a full year before anything is even brought to trial.

TOOBIN: Well, I would say two general areas. One is the communications between both brothers and the outside world. What were their cell phone records, what were their e-ma e-mails, who were they in communication with? That's obviously a huge part of the investigation.

The other part is scientific. It's going to take a tremendous forensic effort to identify just how these bombs were made, where they were made, what the raw materials were, whether they can prove that the brothers bought them, assembled them, all of that is extremely complicated and time-consuming, and that's where I think a lot of the time will go over the next few months, as the government seeks to show how this crime unfolded in precise detail.

COOPER: Jeff, I appreciate your perspective. Juliette, Drew, Dr. Sanjay Gupta, thanks. We will see you again at the top of the 10:00 hour for all the latest developments. There's a lot, as I said, to report tonight, a lot of details on this case. Let us know what you think where the investigation now stands and what you've been seeing over the last week or so. Follow me on twitter @andersoncooper.

Just ahead, has Juliette just mentioned, more on the suspect's Russian connections. Nick Paton Walsh is there in Dagestan looking into that talking to relatives and checking out any possible radical influences.

And later, what the two suspects simply could not destroy a young dancer's hope.

(BEGIN VIDEO CLIP)

UNIDENTIFIED FEMALE: I woke up and my parents were there and I hugged them and kissed them and I said mom, can you help me, I feel like my foot's falling asleep because it feels like my ankle is falling off of the pillow and my foot is half on. And I realized that now that was phantom pain because she looked at me and said you don't have a foot.

(END VIDEO CLIP)

(COMMERCIAL BREAK)

COOPER: Welcome back.

This afternoon, senior legal analyst Jeffrey Toobin said the case against the surviving suspect is about the farthest thing possible from a who done it. Big question for investigators, as Jeff said, is motive, especially concerning how his older brother became radicalized and where. Did it happen last year. Did it happen year in the United States or when he spent January through June back in Russia. Their father, who still lives there, simply doesn't believe any of it.

(BEGIN VIDEO CLIP)

ANZOR TSARNAEV, FATHER OF BOMBING SUSPECTS: My kids never did anything. That's it.

UNIDENTIFIED MALE REPORTER: Sir, your sons didn't do this?

TSRANAEV: Never ever.

(END VIDEO CLIP)

COOPER: The father spoke with CNN international's Nick Paton Walsh who joins us now from the region. Also joining us, former CIA officer Bob Baer.

So Nick, what do we know about what the older brother did in the six months that he was back in Russia last year?

NICK PATON WALSH: Well, speaking to the aunt, although he arrived here according to U.S. officials in January, she wasn't aware of him turning up until March, so it's a slight gap where we don't know quite where he was. He then hung around family members here, making perhaps a couple of trips to see relatives in Chechnya, less suspicious as much (INAUDIBLE) is now moved here to Dagestan. He appears to have been joined by his father in roundabout May as well. But the key thing, the aunt noticed, was how much he had changed from the five years before when she had seen him, he had been that time during in America and had become a very devout Muslim, she said, saying it should be in the very center of his life. And he actually refused to even look women he wasn't related to in the eye. And then, after of course his return to the U.S. in July, we do know that on his You Tube channel, he posted a link to extremist militant video here in the north caucus in Dagestan, a man called Abu Dojan (ph) who subsequently in December was shot dead in a very violent encounter with Russian special forces, Anderson.

COOPER: Bob Baer, you say there's a good chance the older brother had some experience with explosives. What do you think -- where do you think he would have gotten that, overseas?

ROBERT BAER, CNN CONTRIBUTOR: Anderson, absolutely. I mean, you know, we may look at him as bumbling, he got caught and the rest of it and they got their pictures put up on the Internet, but the point is these two young men knew what they were doing. Look at the pursuit. They were throwing grenades out of the windows. That's a classic tactic used to hold back a police pursuit. It's taught by intelligence agencies, by terrorist groups. The fact that they set two bombs off 12 seconds apart, was that done with a cell phone. Their timing was all too good and there were few accidents that I could see.

You don't pick up that sort of expertise in rural Massachusetts or in Boston. You don't learn it off the Internet. You go to some place like Dagestan where there are people that are trained in this that have field experience, hands-on, and this is a hypothesis, but it's almost certain that he learned this stuff in Dagestan or Chechnya.

COOPER: So Bob, let me push back on that, because there are people who say a lot of this information is stuff you can get on the Internet, how to construct these bombs, it's possible they tested bombs here, isn't it?

BAER: Anderson, not in Massachusetts. You know, on these fuses on the grenades, improvised grenades, I mean, how do you light them? Under pursuit? I mean, you would have to know to use the car lighter, you would have to know how long the fuse was.

I've spent the last week talking to people who build these things for a living, and every one of them has said no, you cannot pick this stuff up on the Internet and make it all work. Yes, a lot of it's there, but not to this degree. I just don't believe it. You know, this is speculation at this point, and they may have gotten lucky but I don't think so.

COOPER: Nick, obviously the region Dagestan, Chechnya, has seen a lot of insurgent separatist movements, also terrorist movements, but they have not to my knowledge so far been focused on the United States. Isn't that correct? WALSH: You're right. That is the case, absolutely. In fact, the caucus emirate, the kind of overarching body for many of fraction of the extremist rebel groups here put out a statement denying any connection, in fact, saying it was all part of some conspiracy by the U.S. and Russia to frame them.

But since the second Chechen war, the extremism here particularly during a Russian clamp-down has become much more fractured. Some of the younger generation here do include threats against the United States in some of their bolder statements. Wholly unrealistic given that actually a lot of the time they struggle to hit their main target, Moscow, here in Russia.

That Russian presence and military, always their main target but the occasional feeling among some of the statements we've seen that the U.S. could be perhaps an aspirational target -- Anderson?

COOPER: Interesting. We will talk to you guys both again in the 10:00 hour for more on this investigation.

Coming up tonight right now, Tamerlan Tsarnaev leaves behind a wife, a young daughter. Now the FBI wants to know whether his wife had any idea about what her husband was allegedly planning. What we now know about his wife and his relationship. That's coming up next.

Also ahead, I spoke with a young woman today in the hospital, a remarkable young woman and her husband. She's a dance instructor. She lost part of her left leg below the knee in the bombing. Determined she is to dance again and even maybe to run the marathon next year. I want you to hear from her. You will have no doubt that she could do just that.

We will be right back.

(COMMERCIAL BREAK)

COOPER: We are learning more and more about 26-year-old Tamerlan Tsarnaev, who was killed early Friday morning. He's married -- he was married to a woman named Katherine Russell, who is 24-years-old, and she's been staying with her parents in Rhode Island. Her attorney says she didn't know anything about what her husband was allegedly planning and learned that he was a suspect actually from watching news reports.

Chris Lawrence joins me live from Rhode Island with more on what we know right now about her.

Chris, I know you spoke to her family's attorney. What did he say about what she's doing and about how she's doing?

CHRIS LAWRENCE, CNN PENTAGON CORRESPONDENT: Bottom line, Anderson, he said she is cooperating with the federal authorities. We know that federal agents have been here to her parents' house several times over the last couple days. In fact, there was a federal agent, a car parked right down the street for several hours today. Federal agents have also escorted her from the house at least once today. He says basically she understands why they want to talk to her, why they want to know if she knew anything at all about what her husband was doing, and if he had any other affiliations besides his younger brother. He says that the wife, Katherine Russell, didn't know anything about this. He said basically quote "the family is a mess."

He told me that Katherine Russell is distraught. She is crying a lot.

She feels horrible about what's happened to the victims of the Boston marathon bombing and he said at the same time, she's also dealing with the fact that she has lost her husband and the father of her young daughter so a lot of emotions obviously for this young woman -- Anderson.

COOPER: Do we know how she met Tamerlan Tsarnaev and how her life changed after that? Because there had been a report that years ago he had had a girlfriend who he had allegedly slapped, she had dialed 911. That is not the woman he ended up marrying, correct?

LAWRENCE: Yes, we don't think so. I took a look at that court report and saw that allegation, that domestic violence allegation, but the victim's information is all blacked out on the court document.

I can tell you that basically, she was in college when they met. They got married back in 2010. They have a young daughter who is only about two-and-a-half years old. Basically, Katherine, the attorney says friends knew her as Katie.

She basically was raised as a Christian. She converted to Islam when she met Tamerlan, and she is somewhat observant. She wears the head scarf normally, but he said she was in a bit of a tough spot

That because Tamerlan wasn't working full-time, he said Katie Russell was basically working up to seven days a week, sometimes 70 hours a week as a home aide, so Tamerlan would stay home and take care of their young toddler daughter while Katie Russell went out and worked for most of the week -- Anderson.

Now, Toronto, Canada where Paula Newton has late details of a terrorist plot that authorities in Canada say they have foiled. They say it involved an al Qaeda supported attack against a passenger train traveling between Canada and the United States.

Paula, this plot has got a lot of interesting elements. It was directed, supported allegedly by al Qaeda in Iran. Have we seen that before?

PAULA NEWTON, CNN INTERNATIONAL CORRESPONDENT (via telephone): Not seen that at all before, especially lately since basically al Qaeda and Iran have had a rift considering the situation in Syria. It is very strange to see that here.

Iran for its part doesn't want to be associated with this and they do not support it. Having said that, Anderson, the police were pretty clear this was they say guided and supported by al Qaeda in Iran.

As you said, Anderson, lots of different elements. The key one being that they were under surveillance for months. Authorities went to pains to underscore there was no connection to the Boston bombings.

There was no imminent attack, but in fact, this was a threat of a real attack. How do they know that? From having listened in on them for months now. The key now, Anderson, is look for what the evidence shows and search warrants they have executed.

They have a bail hearing in the morning in Toronto and we'll have a good look at what they found hopefully in some of those addresses. Those search warrants are being executed as we speak -- Anderson.

COOPER: Do we know how many people were involved in this alleged plot, and also, how were authorities able to catch them?

NEWTON: Right now, two were arrested, one in Toronto, one in Montreal. They say this is an open investigation. They do not rule out that more will be arrested. Basically, it was the surveillance but it's interesting, Anderson, they were again underscoring the fact that the first tip, the very first tip, came from the Muslim community itself.

Anderson, these two are not Canadian citizens. They came to Canada several months ago, perhaps a couple of years in order to study and work, but they are not Canadian citizens and yet, the Muslim community believes they did tip them off, let them know exactly who to investigate.

And when they went looking, Anderson, they got those warrants to be able to basically put on those wiretaps, they found what they say really was -- could have been a chilling attack in Canada on those trains.

COOPER: Interesting. Paula, appreciate it. Paula Newton reporting.

Just ahead, one of the Boston bombing survivors, a really remarkable young woman, I spent time with her in the hospital with her today. Young dance instructor. She describes what it was like to come out of surgery and be told they couldn't save her foot.

She says she will dance again. She's got a great attitude concerning what she's lost. She would be the first to tell you her anger is very real and very justified.

(BEGIN VIDEO CLIP)

COOPER: Are you angry?

UNIDENTIFIED FEMALE: I am angry, yes. I am angry. Yes. I'm angry. Yes. I'm mad that this happened. I'm mad this happened to me. I mean, that sounds selfish, but I think Adam's mad it happened to him, too.

(END VIDEO CLIP) (COMMERCIAL BREAK)

COOPER: Welcome back. Tonight, one week after the bombing, 50 of the wounded are still hospitalized. Two of them remain in critical condition tonight. At least a dozen survivors have had to have amputations.

Today, I met Adrienne Haslet-Davis. She lost her foot -- excuse me, she lost her foot and part of her lower leg. She's a dance instructor, 32 years old. She told me that dancing is her life. You can see her passion when she talks about it.

Adrienne was watching the marathon with her husband, Air Force Captain Adam Davis, who has served in Afghanistan and Kandahar. They were hit by the second blast. Adam was also injured, though not as seriously, thankfully. They're an amazing couple. I spoke to them both earlier today.

(BEGIN VIDEOTAPE)

COOPER: I hate to ask you to relive what you went through so if you don't want to, that's totally fine.

ADRIANNE HASLET-DAVIS: I was right in front of it, right in front of the business where it was, so I felt the direct impact and it immediately blew off my left foot.

COOPER: How far away was the bomb? Do you know?

ADAM DAVIS, BOSTON BOMBING SURVIVOR: My guess would have been about five feet.

COOPER: Five feet.

ADRIANNE HASLET-DAVIS: Yes. We're lucky to be alive.

COOPER: Did you lose consciousness?

ADRIANNE HASLET-DAVIS: I don't think we did. I remember everything so if we did, it was for a matter of seconds.

COOPER: You remember being blown through the air?

ADRIANNE HASLET-DAVIS: Yes, I remember the air hitting me and the impact of the air hitting my chest and stomach and flying through the air and then landing. I have a giant bruise on my left side and sore shoulder from landing. COOPER: What happened then?

ADRIANNE HASLET-DAVIS: I landed and sort of closed my eyes and was underneath Adam and kind of covering my head and my face. It was very gray and quiet, gray smoke and ashes and a lot of debris falling, and I remember telling Adam, my gosh, I'm alive, and then he said I'm OK, I'm OK, are you OK.

My gosh, are you OK? I said I think we're OK. I couldn't believe it. I couldn't believe that we survived, and that we weren't hurt at all and I didn't feel any pain. I had no idea what had happened.

And then I sat up and I tried -- he said we've got to get out of here or something like that. I sat up and tried to move, and I said, my gosh, my foot. There's something wrong with my foot. He lifted up my leg and we just lost it.

COOPER: So you got to the hospital.

ADRIANNE HASLET-DAVIS: Yes.

COOPER: What happened?

ADRIANNE HASLET-DAVIS: Got to the hospital and they were clearly, you know, just -- I was conscious all the way through it and getting into the hospital, and them opening up the doors, it was clear that they were -- how many beds, where do we put people. It was clear that they were very -- very busy and taking in a lot of people. And they brought me right in and right before I got to the hospital, as I was laying on the ground waiting for which ambulance I would be put in, because they had me on a board.

They were writing numbers on the foreheads of importance at the hospital, and I just prayed that I had a number that meant take me now, which apparently I did. So when I got to the hospital they saw me right away.

And they kept propping up my foot and tying a tourniquet, trying to tie it together, and shooting me up with pain meds, as many pain meds as they could.

COOPER: At what point, I know your mom came, mom and dad, and you woke up I guess the next day.

ADRIANNE HASLET-DAVIS: Yes. They were there when I woke up the next day so I thought it was still the same day. I'm still a little foggy on days, but they were there the next day, when I woke up. When I went into the surgery, I still thought they could save my foot.

I could move my toes. I could feel them touching my toes. They said wiggle your toe, do you feel your foot? I could still do it so I thought that in my forever optimism and thinking positive that I would still have my foot and woke up and I didn't.

COOPER: When did you realize you didn't have your foot? ADRIANNE HASLET-DAVIS: I was -- I woke up and my parents were there and I hugged them and kissed them and I said mom, can you help me? I feel like my foot's falling asleep because it feels like my ankle is falling off of the pillow and my foot is half on.

And I realized that now that was phantom pain because she looked at me and said Adrienne, you don't have a foot, your foot is gone. I just lost it. It was really hard to hear.

COOPER: You're determined to dance again.

ADRIANNE HASLET-DAVIS: I am. Yes.

COOPER: Dancing is really important to you.

ADRIANNE HASLET-DAVIS: It is so important to me. It's my life.

COOPER: What about it?

ADRIANNE HASLET-DAVIS: Dancing is the one thing that I do and I've said this many times, but dancing is the one thing I do that when I do it, I don't feel like I should be doing anything else ever. I feel so free and so wonderful. I'm big on music and I feel like all of us, when we hear music, we kind of move to the music and I feel like --

ADRIANNE HASLET-DAVIS: That's OK. I'm going to hold you to that. Now it's on camera. But I feel like it's just such a freeing thing, it's such a big part of my life and part of my life also is being able to teach people how to do that.

So not only is it big in my life for me, an outlet for me, I get to share that and see it developing in other people, and most of the flowers that are in my room right now are from students that have appreciated what I've taught them and what Arthur Murray in general has taught them. I think it's really important.

COOPER: You're incredibly optimistic.

ADRIANNE HASLET-DAVIS: Thanks. I try and stay optimistic. I think that you have two options. For me, I think that everything in life is pretty -- has always been pretty black and white to me.

That's just me personally but I think you either -- I could either stay in bed and cry and be really upset and I do have moments of that, or I can say I'm going to, you know, run the marathon next year and conquer and be good.

COOPER: You want to run the race next year? ADRIANNE HASLET-DAVIS: I do. I can't believe I said that. Adam's been making fun of me the whole time. He's like I can't believe you said that. You're not a runner at all.

COOPER: So you're not a runner.

ADRIANNE HASLET-DAVIS: I'm not a runner at all, no. But I wasn't a ballroom dancer at one point in my life either.

COOPER: So you're going to do it.

ADRIANNE HASLET-DAVIS: I'm going to do it. Yes.

COOPER: I hope to be on the finish line watching you.

ADRIANNE HASLET-DAVIS: Thank you.

COOPER: Let's say I hope to be running with you, but I'm in such bad shape.

ADRIANNE HASLET-DAVIS: That's OK. We'll conquer dance lessons this year and do the marathon next time.

COOPER: Sure. OK, little by little.

ADRIANNE HASLET-DAVIS: Little by little.

COOPER: If you can get me dancing and running I will be very amazed.

ADRIANNE HASLET-DAVIS: If I can get me running I'll be very amazed.

COOPER: Are you angry?

ADRIANNE HASLET-DAVIS: Yes, I'm angry. I'm not angry 100 percent of the time, but I'm angry. I think when someone tries to stop you from doing something or something happens in your life where it's not exactly what you expected, you have to conquer that and you have to -- you have to find the better side of it.

It's not something that -- I don't know, I don't want to -- I don't want that to be the end. I don't want this to be the end. I'm only 32. I don't want this to be the end. So whether it's, you know, running the marathon or walking the marathon or crawling the marathon and being the last one across, I'm OK with that. I didn't say I would win it, but I am defiant and I want to -- I want to come out stronger.

COOPER: She is an amazing young woman as is her husband. They have set up a fund to help her legal costs and also the cost for her prosthetic devices that she will need. It's run by the Arthur Murray Dance School.

It's www.gofundme.com/adriennefund. So it's gofundme.com, all one word, slash adriennefund. We'll also have that web site up on her web page, ac360.com, again, Adrienne, amazing young woman. We hope she starts dancing really soon. I do hope to take some lessons from her.

Just ahead, inside the end game, the SWAT team that helped put the Boston bombing suspect in handcuffs describes how those final minutes of his capture played out, their first national interview coming up.

(COMMERCIAL BREAK)

COOPER: Today, I spoke to some of the members of the SWAT team who risked their own lives and actually put Dzhokhar Tsarnaev in handcuffs on Friday. Here's a shot of Tsarnaev as he's leaving the boat, just before he was handcuffed by the SWAT team.

They're going to talk about that moment where he was sitting on the edge of the boat, rocking back and forth. It was a very dangerous, tense, tension-filled moment for the SWAT team. As the case is with heroes, the members of the SWAT team I talked to don't want to take all the credit for capturing him.

When I spoke with them today, they kept making the point over and over this was a team effort involving many agencies, state, local and federal, first responders who also needed to be thanked. They're not after attention.

This is the first national interview that the SWAT team for the Massachusetts Bay Transportation Authority was given. Here's some of what they told me today.

(BEGIN VIDEOTAPE)

COOPER: Tell me about Friday night. When was the first indication you got that the suspect had been found?

OFFICER JEFF CAMPBELL, MBTA TRANSIT POLICE SWAT: We gathered up the men that we had left at that point and we started rolling to that location to help in any way that we could. We got out there and several agencies out there, already the suspect was cornered and had been hiding in this boat.

Different agencies that were on scene were trying less lethal means to get the subject to turn himself in. I believe they tried numerous flash-bang grenades. They tried some -- they tried to gas him out of the boat. Just wasn't working.

COOPER: Did you know at the time whether the suspect was conscious or not?

CAMPBELL: We were getting reports from I believe it was the state police helicopter, stated reports from them there was movement inside the boat. They were using the infrared to look through the canopy, the tarp that was on it.

COOPER: They have released those images. We have seen the infrared images. They could tell -- because there were reports that sometimes he was moving, then sometimes he wasn't moving.

CAMPBELL: Correct. OFFICER SARO THOMPSON, MBTA TRANSIT POLICE SWAT: He was going in and out of consciousness because he was losing a lot of blood.

CAMPBELL: Which is how the homeowner actually found him was from a blood trail leading up to the boat, he saw a slice in the canopy so he took a peek inside. That's when he saw the suspect inside the boat and made his 911 call.

COOPER: But at that point did you know if he was armed, if he had explosives on him?

THOMPSON: He had gone into a fire fight earlier that day with some of the officers who responded to that scene after the 911 call, some of our patrol officers. And we know for sure there was a weapon there.

CAMPBELL: You have to assume with the events of the last week that there were explosives as well.

COOPER: So you guys get together to come up with a plan. What was the plan? What was the idea?

CAMPBELL: It was basically just to get across that danger zone. There was an open area from where the house was that was our final line of cover if he stops firing at us. We have no protection getting across that danger zone. So we had a Kevlar shield up in front of us and we all lined up in a stack behind that shield to cross that danger zone.

COOPER: Were you thinking you're going to have to go into the boat to come out or was your understanding he was going to come out?

CAMPBELL: It was our understanding he was giving himself up. He was sitting on the edge of the boat with one leg hanging over the side.

COOPER: When you first saw him, what did you think?

CAMPBELL: This is the target, this is the job, you know. We're almost done with this and let's do it. Let's just do what we're trained to do. This is the suspect. We're trained to go in and apprehend him.

You could see one hand was clear of any weapons, but each time he went back the other way, his hand went down inside the boat out of our view. And I know everybody here, we've spoken about it, each time he did that, we had to assume that he was reaching for either a weapon, a firearm, or some type of explosive ignition device to try to draw us in and then take us out in a suicide type manner.

He did that a couple of times, as we were still approaching towards him. We got close enough that at one point, where both of his hands were up, because of the rocking back and forth, both of his hands were up, we could see that there were no weapons in them, no ignition devices, we broke away from the shield protective cover and we just rushed him.

We put hands on him, grabbed him and pulled him off the boat. Down on to the ground. At that point, it just became I don't want to say typical, but an arrest situation. You check the suspect for weapons. Of course him, we had to check him for explosives, take his sweatshirt off because he may have been wearing a suicide vest.

At that point, we still didn't know if the boat had been rigged with explosives, some type of timed device or anything like that just because of their behavior all week long. So at that point we needed to get him away from the boat.

As soon as he was checked for anything, handcuffed, we picked him up and ran like hell to get away from that boat. And got him over to where the medics are and the federal agents, who were taking him into custody.

COOPER: There's a report that he was shot in the throat. Unclear whether that was self-inflicted, or at what point -- could you tell that?

CAMPBELL: I did see a throat injury. To me it looked more like a knife wound. It wasn't a puncture hole. It was a slice where it was spread open, possibly a piece of shrapnel from one of the explosives that they were using the night before. It didn't look like a bullet wound to me. It looked more like a cut of some kind.

COOPER: What goes through your mind? You were focused for a week on finding this guy. You've seen horrible things on that Monday, you know, you've been working around the clock. To know that he's finally apprehended, what does it feel like?

SGT. DET. SEAN D. REYNOLDS: It's a relief, but we're not sure it's over yet. We're still on that mode. We've still been working, we haven't had a chance to really sit down, watch the news and think about it and see what's actually going on. So we're still in that heightened state as I'm sure everybody is, and maybe in a couple weeks we'll get a chance to sit down and reflect on what actually happened.

(END VIDEOTAPE)

COOPER: A remarkable group of law enforcement professionals. It bears repeating, team members call what they did a group effort, state, local and federal officials. They say they were simply doing what they were trained to do.

One note about the MBTA officer who was shot during the chase last week, we understand he's still in serious condition. There is a fund set up to help him. It's officerricharddonahue.com. You also can find that on our web page, ac360.com. We'll be right back.
